Origins of nervous system found in genes of sea sponge, report scientists at UC Santa Barbara

(Santa Barbara, Calif.) -- Scientists at the University of California, Santa Barbara have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals.

The findings are published in the June 6 issue of the journal PLoS ONE, a Public Library of Science journal. The article can be found at http://www.plosone.org/doi/pone.0000506.

It turns out that sponges, which lack nervous systems, have most of the genetic components of synapses, said Todd Oakley, co-author and assistant professor in the Department of Ecology, Evolution and Marine Biology at UC Santa Barbara.

Even more surprising is that the sponge proteins have signatures indicating they probably interact with each other in a similar way to the proteins in synapses of humans and mice, said Oakley. This pushes back the origins of these genetic components of the nervous system to at or before the first animals much earlier than scientists had previously suspected.

When analyzing something as complex as the nervous system, it is difficult to know where to begin, explained Ken Kosik, senior author and co-director of UCSBs Neuroscience Research Institute, who holds the Harriman Chair in Neuroscience Research.

The first neurons and synapses appeared over 600 million years ago in cnidarians, creatures known today as hydra, sea anemones, and jellyfish. By contrast, sponges, the oldest known animal group with living representatives, have no neurons or synapses. They are very simple animals with no internal organs.

We look at the evolutionary period between sponges and cnidarians as the period when the nervous system came into existence, about 600 million years ago, said Kosik.

He explained that the research group made a list of all the genes expressed in a
